ʻO ka paʻakikī o ka nitrogen o Nitrogen-loaʻa i nā huapalapala fuplex i loaʻaʻole mai nā mea kila austentite kiʻekiʻe.
ʻOiaiʻaʻole e pale akuʻo Nitrogen i ka hana maʻamau o keʻano, e kau ia ia, ʻaeʻia ka manawa kūpono no ka hoʻoiliʻana a me ka hanaʻana.
Hoʻohuiʻiaʻo Nitrogen i nā mea hoʻokūkū kiʻekiʻe-corrosiod austetentic a me nā kinipōpō maikaʻi a me nā molybdex.
Nitrogen, he mea hana ikaika ausdite-forming, hiki ke hoʻololi i kekahi nickel i loko o nā kila austenitic.
Hoʻopau ia i ka ikaika o ka ikaika a me ka hoʻonuiʻana i ka helu hana-paʻakikī o Austente.
E hoʻonui nō hoʻi ia i ka ikaika austentete ma o ka hoʻoikaika paʻaʻana.
Hoʻokomoʻia nā mea hoʻokūkū Fuplex i nā nitrogen a ua hoʻoponoponoʻia kā lākou nūpepa Nickel e hoʻokō i ke kaulike kūpono.
Ke kaulike nei i nā mea hana frarite-forming (chromium a me molybdenum) me nā mea ausdite-forming (nickel a me nitrogen) he mea pono no ka hoʻokōʻana i kahi hoʻolālā duplex.
Nickel
ʻO Nickel Stabilizes Austenteite, Ke hoʻolauleʻa nei i ka hoʻololiʻana o keʻano o ka crystal mai ke kino kino kino (Bcc) ʻO Ferrite e hoʻokūkū i ka cubic (Fcc) austentes.
ʻO nā mea hoʻokūkū Ferritic Ferritic, ʻOiaiʻo Dulex Duplex i nā mea hele a Friplex i loaʻa i kahi haʻahaʻa o Nickel, maki 1.5% i 7%.
Austetitic stickless austeticitic i loko o ka 300 Loaʻa nā hanana ma ka liʻiliʻi 6% nickel.
Hoʻokomoʻiaʻo Nickel i ka hoʻokumuʻana i ka hana o nā hana maʻamau ma waena o Austelitic Stiint, ʻOiai ua emi iki kēia hopena ma Duplex i nā mea hoʻokūkū Duplex i hoʻohālikelikeʻia i nā nitrogen.
Ke alo o ka maka (Fcc) Hāʻawi keʻano i kahi kila kila austenitic.
Mai ka hapalua o ka hapalua o keʻano ma Duplex Insinless Steel, ʻO ka Steel Dulex Steel he mea nui loa ia ma mua o ka mea kila ferritic.
